Be it known that I, JULIUs HANSEN, a citizen of the United States,residing at Coiegvilla in the countyvof Montgomery and tate of Kansas,haveinvented certain new and useful Improvements in Agitators forMineral Oils, o f which the fol-- lowing isa specification, referencebeing had to the accompanying drawings.

'lhis invention relates to certain improvements iii methods of'treatingmineral oils and it is an object of theinvention to provide .a novel andimproved method for birleaking'or cracking heavy oil into lighter o Itis also an' object of the invention to provide a novel and improvedmethod wherein kaolinite is mixed with the heavy oil when within thestill and wherein scraping means is employed for the proper handlin ofthe kaolinite and to prevent coking of t e still.

and have scraping action upon the inner The novel features of theinvention hereinafter be definitely claimed.
